in's'ection and the stay wires being shown in a cond tlo'n immediately preceding cutting from the supply; Flg. 3 a fragmentary:

view similar to Fig. 2, the stay wires being shown in condition immediately following cutting from'the supply 'and'immediately preceding twisting; Fig. 4 a view similar; to Figs. 2 and 3 with the parts in theposition immediately following twisting and just preceding advancement of the running wires and attached stay wires; Fig. 5a fragmen tary elevation of a running wire and the twoas'sociated stay wires; Fig. 6 an elevation similar to Fig. 5 in a plane at 90 degrees "therefrom; Fig. 7 a vertical section on line i and associated parts at the end of the twist- 77 of Fig. 2 with the parts in position immediately preceding cutting and bending-of the stay wires; Fig. 8 a vertical section of the parts shown in Fig. 7 with the parts in position immediately following cutting and bending of the stay wires; Fig. 9 an eleva-' tion of the parts shown in Fig. 8 with said parts in the positions shown in Fig. 7; Fig. 10 a fragmentary elevation of a twister head ing operation; Fig. 11 a plan, somewhat distorted, of the stay wire feeding andtwisting means and Fig. 12 anelevation of one of the stay wire holders and adjacent parts.

In the drawings 20 indicates the main frame through which the running wires 21. are threaded oversuitable supports 22' and advancing means'23, said parts being common and well-known in the trade and the details thereof forming no part of my present invention.

Each running wire is threaded axially through a twister head 30, of well known form, said twister head having at its end two eccentric pins or shoulders 31, 31 spaced from the bore, through which the running wire passes, a distance'slightly greater than the diameter of the stay Wire which is to be- 1927.

attachedfto' the running-wire "which passes through the bore.

Each twisterhead is provided with a shank 35' which is journaled. in i the main frame 20, and in a bracket 36 securedjthereto,

' andeach shank is" provided with a'pinion 37 which meshes with one set of teeth ofa dou ble rack 38' slidably mounted on the main frame. "Theother set ofteeth of rack 38 meshes with a pinion 40 journa led on across head ll whichis reciprocablymounted in a slot 1-2 inthe'm'ain frame 20 and is connected by a link 43 with a lever 44 pivoted at 45"..

Qlithe main rame and intermittently recip rocated by a cam 46 onshaft 47 jou fl d in the mainframe. Pinion 40 also meshes with a fixed rack 50 mounted on the mainframe Arranged between each pair of twister headsis a two-part stay-wire holder, shown in detail in Fig. 12.1 This holder comprises a stationary portion across the face off 7 which is forme'da half groove '56 having a diameter slightly greater than the diameter of the stay wire 32 which is to be used. As sociated with the portion 55 is a. hinged'p'ortion 57 the inner face of which is likewise provided with a transverse groove 58 which:

registers with groove 56. At the receivingf' I end of the groove or wire 'guide 56.-5 8-it is flared outwardly, as indicated in Fig. 12.

Portion 57 is 'yieldingly urged against/J g tion 55 by a spring 59.

Leading. to each of the stay wire holders j ust described' but spaced therefrom by an intervening twister headis a guide tube 60* at the end of whichis a cutting die '61 through which the stay wire is threaded, said die being so placedand "directed that a stay wire projected through the guide tube'will pass between the running wire and'one of the'twisting pins .31 of thejadjacent twister several feed wheels 62 are carried by a shaft 6 L which is intermittently advanced by a are so spaced and arranged that, as shaft 75,

"Arranged alongside of the series of twister heads is a rock shaft upon :which is mounted a series of cutter and bender heads 76, one for each twister .head. Each bender head carries a. combined cutter and bender finger 77 and a bender finger 7 Swhich fingers is rocked (in a counter-clockwise direction, Fig.7) finger .77 will cooperate with die 61 t cut the'stay wire running- 'thcrethrough and to ,then bend said stay wire down upon an inclined surface 79 on the twister head 30, and finger 7 8 will engage the free endof the associated stay wire 32 and bend it down' upon the downwardly inclined surfacev 80 on twister head30 diametrically opposite surface 79.

means of a pitman connected to a lever 91 actuated by a cam 92 on shaft47. i

The operation isas follows: The twister heads. being in the positions indicated. in, Fig.2, the ratchet mechanism 65 willactuat-ethe several stay wire-feeder "wheels 62 to project through each tube-60 an amount of stay wire suflicient to bridge the space between the adjacentpair of run- 7 ning wires and to: furnish, beyond each of saidjrunning'wires, a sufficient quantity of V stay wir'e for the twist or wrapping of the.

stay wire about the adjacent runningwlre, each stay wire being projected through a two part stay wire holder 55* 57. 7

Shaft 75. will then. be rocked to 'cause,.in

the manner already described, a cutting and bending of stay wire portions, each supported inits two part ho1der,and will then be returned to the position shown in F ig. 7.-

Thereupon cross he-ad'el will be reciprocated so as to rotate thetwister heads 35 a suificlent number of times to twist the free ends. of the stay wire sections around." the adjacent running wires as illustrated in F gs. 5, 6 and 10. Thereupon the running.

A wirefeeding mechanism 23- will be actuated to advance the running wires one stepin the machine, the yielding sections 57 of the stay wire holders yielding toflpermit thewith Shaft '75 intermittently rockedc by drawal' of the stay wire sections therefrom.

While the'running wiresare being thus advanced the stay wires are being again pro jected inv the manner already described and 3 the v operation is repeated.

I claim as my invention: l. Inamachme for producing w re tab ric, the combination with means, for support- I ing and forwarding a series ofrunnmg wires, a series of stay-wire twister heads. through each of which a running wire passes, means for intermittently rotating the said twister heads, and means for as;

and means l'or intermittently actuating said} stay-wire cutters.

the combination with means for supporting and forwarding a series ofrunning wires, a

series of stay-wires twister heads through each of which a running wire passes, means for intermittently rotating the said tWlStGD' heads, and means for associating stay ,wires 1 with the running wires through the medluin of the twister heads, said meanscomprismg,

means for intermittently actuating said stay wire cutters and benders.v p p .7

In witness whereof, I have, hereunto set my-hand at Anderson, Indiana, this 23rd day of May I D. one thousand nine hundred and twenty-seven.
